So, this evening I sharpened my three new Yamawaku knives. First, I have to say that it is very cool to do, but I don't have to tell that to this group. Putting a better edge on a knife feels like I am actually accomplishing something. BUT, I also learned a lesson about attentiveness. After finishing the Nakiri I ran it through the deburring felt block. As the blade exited the block, it dropped just a bit, less than a couple of inches, and the rounded front edge bounced against the end of my pinky. In the past with my old knives this would have done nothing, and at first glance it appeared to not have done any damage. At first glance. After a couple of seconds, holy cow, you would have thought I struck an artery. After a lot pressure, some gauge and tape, everything is fine, but, wow. The cut is less than half an inch long, but it went in pretty deep. With virtually no effort. Pretty impressive, actually. Think tomato skin. Note to self - NEVER lose concentration when working with these knives, either cutting or sharpening. All three Yamawaku knives are now seriously sharp. Have started comparing Konosuke to Yamawaku to Moritaka and will continue the experiments through the holiday weekend, as I am finally around for a few days and can do some cooking. Will report my experiences, once I think I have something of interest to contribute.
